Ever get tired of buttoning up the fly of your BDUs? While buttons have the convenience of being easily repairable in the field, zippers are not only more convenient to use, they are faster, and were all used to them. So trade in your old button BDUs in for these new zipper fly BDUs. They have the same six pockets you have come to expect, same adjustable waist tabs, reinforced seat and knees, and ankle draw strings, but they also have a wider, slightly baggier leg than the mil-spec BDU. We think this makes the more comfortable and less constricting. Great for casual every-day wear as well as tactical use!
